If this concept is still foreign to you, here is Baxter’s fun analogy to Lord of the Rings. She says, “Imagine the nasal cavities are Saruman’s orcs, building pits of flame. It takes a while to create enough invaders to march down to the throat, then the lungs. During the five days of non-smelling, headache, and/or sore throat as the rose-crowned orcs multiply, imagine flushing the whole works out twice a day.” This “gives the immune system time to figure out what it needs while reducing the enemy.”

In summary, nasal irrigation may be effective in avoiding respiratory problems arising from COVID-19. Flushing the sinuses can stop the virus from spreading to your lungs and causing damage throughout the body. A nasal wash is a safe and risk-free solution to try.
